Abstract:
Tri-calcium phosphate, a source of insoluble phosphateand different sources of nitrogen and carbon were used to study the phosphate solubilizing capacity of Pseudomonas lurida (Psychrotolerant strain). Tri-calcium phosphate solubilized in different carbon sources and incubation times, such as ambient (30 °C) and 10 °C, in the following order: glucose > maltose > galactose > sucrose > xylose. With all carbon sources and TCP presence, the pH shifts from being neutral to acidic. When TCP was solubilized with various nitrogen sources, ammonium sulphate caused the greatest amount of solubilization to occur. With glucose as the carbon source and ammonium sulphate as the nitrogen source, Pseudomonas lurida exhibited its highest level of phosphate solubilizing activity. In a liquid media, TCP solubilization was noticeably high.
